Celebrities turned out en masse for this year's U.S. Open, but some were more amenable to the public setting than others. For instance, Leonardo DiCaprio apparently hid under his cap and ducked under a table when cameras were pointed at him. Justin Timberlake and Jessica Biel, on the other hand, were only too happy to give the public what it wanted.

On Monday, the couple cozied up at the men's final, where the actress was snapped planting a sweet kiss on the cheek of her pleased-looking husband as they watched Rafael Nadal defeat Novak Djokovic.

Perhaps their PDA was part of marking a marital milestone. Life & Style says Biel has officially taken her husband's famous last name, although she'll continue to use her maiden name professionally.

"The paperwork is done," says an insider, "and she's now legally Jessica Timberlake."

The name change has been in the works since their lavish October 2012 knot-tying.

"I think it sounds great," Jessica gushed about her new moniker shortly after the nuptials. "I think I really won the jackpot of names."
